Device and method for measuring angles and conveying these measurements to a processing apparatus

Abstract

The present invention consists of a device ( 1 ) suitable for use during molding work for the measurement of at least one angle formed by at least one first surface and at least one second surface and for conveying the angle or angles to cutting equipment for the adjustment of cutting angles. The device is comprised of at least one first arm ( 2 ) and at least one second arm ( 3 ) which are connected to each other via at least one connecting device ( 4 ) and pivotally arranged in relation to each other via at least one first axis of rotation ( 5 ) and that the device ( 1 ) includes at least one angle indicator ( 36 ) with which the mutual angle between the first arm ( 2 ) and the second arm ( 3 ) is measured. The device ( 1 ) includes at least one unit which indicates a part of angle (V), preferably half of the angle (V), between the first arm ( 2 ) and the second arm ( 3 ) and that this unit is suitable for use in the adjustment of the angle in a cutting machine. The present invention also concerns a method for use of the device.

The invention claimed is: 
     
       1. A device for angle measurement comprising:
 a first arm having a first surface and a first end and an opposing first distal end, 
 a second arm having a second surface and a second arm end and an opposing second distal end, 
 the first end pivotally connected to the second arm second end; 
 the first surface and second surface defining, between them, a changeable mutual angle; 
 an adjustment plate pivotally connected to the first arm at the first distal end and defining an adjustment plate angle with respect to the first surface; 
 an elongated strut having a first and second strut end, the first strut end pivotally connected to the adjustment plate and the second strut end pivotally connected to the second arm; 
 such that the magnitude of the adjustment plate angle remains a predetermined fraction of the magnitude of the mutual angle if the mutual angle is changed. 
 
     
     
       2. A device, according to  claim 1 , and wherein:
 the magnitude of the adjustment plate angle is equal to one half the magnitude of the first angle. 
 
     
     
       3. A device, according to  claim 1 , and wherein:
 the first arm has an interior space extending from the first end to the first distal end; 
 the adjustment plate includes a bracket extending into the interior space; 
 the strut connected to the bracket and extending through the interior space to the second arm. 
 
     
     
       4. A device, according to  claim 3 , and wherein:
 the first arm comprises two mating portions secured together and forming the interior space. 
 
     
     
       5. A device, according to  claim 1 , and wherein:
 the first and second arm together have an adjustable indicator configured to display the magnitude of the first angle.
